Can't quite remember what I have in my truck (as I'm out of town for work for quite a while) but my batteries are about 8 years old, hold a perfect charge over the course of a month or longer and truck has absolutely no problems starting. Ill be interested to see if they are still charged or not when I get back home in a month or 2.

Mine are just now going weak, they're Motorcraft and were installed in early '08. I'll be getting a pair of Interstate MTP-65's to replace them with @ around $130 each. This may be a dumb question but this will be the first time I replace the batteries for this truck on my own, the shop I'm getting the batteries through suggested replacing one at a time in order not to lose any of the memories I have set, can this be done safely without causing any electrical damage to the truck or the batteries?

Yeah I did the driver side then the passenger side. No setting or memories lost. Just make sure positive terminal doesn't touch anything when ya swap them.
